` This invention relates to lsliding defiectors for use upon fold plates of buckle type folding machines.

The fold sections of a buckle type folding machine frequentlyA comprise several fold plates, the paper travelling into. each of these pla-tes in succession where the maximum number of folds in parallel are to lbe' imparted to the paper. Often times, however, the job in hand requires lessV than the maximum number of folds, and it is then necessary to disable one or more of the fold plates. This disabling is effected by covering the nose ofthe plate with a deflector which directs the paper away from that fold plate and into the next succeeding pairof folding rolls. These deflectors are ordinarily hinged to the fold plates and are merely swung from operative to inoperative position Vor vice versa. The hinged deflector plate. is quite satisfactory where plenty of space. is available for it to swing about its pivots.V The necessity for the provision of this space in somecases however is a determining factor as to the spacing of the fold plate away from a feed table or other associated part, preventing as compact a machine as would otherwise be possible.

One ofthe objects of my invention is the provision of a mounting for delectors of this type such that the fold'plate upon which is used may be positioned close to some adjacent part ofthe machine.

. Another object is the provision ofv a mounting for deiectors wherein the deflector moves forward and backward over the surface of the plate instead of swinging thereupon. o

Another object is the, provision of a mounting of this character wherein stops may be employed to prevent accidental movement of thev deflector in its operative or inoperative position and the deflector may berdisengaged vfrom the stops by a rocking movement.

Still another object is'the provisionof pin and slot connectionswhich accomplish `the purposes stated.` ,i

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the presentapplication, I

have illustrated in the accompanying drawings, in which Figure 1 is a longitudinal vertical sectional view taken substantially on the line 1-1 of Fig. 2, illustrating a portion of a folding machine embodying my invention.

Fig. 2 is a plan view of the same, partly in section upon the line 2-2 of Fig. 1, and

Figs.r 3 and 4 are detail sectional views on a larger scale illustrating the deiiector and its fold plate in the operative and inoperative position of theV latter, these sections being taken substantially on the line 3-3 of Fig. 2.

In the drawings the frame of a folding machine is illustrated generally at 10.l A feed table is shown at 11 from which sheets are adapted to be directed over a roll 12 and between guide plates 13 and 14 into a fold section. This fold section comprises folding rollsl, 16, 17, 18, 19 and 20. It also comprises fold plates 21, 22, 2 3 and 24, the course of paper through the fold plates being in the order named, assuming that four folds are to be imparted to the paper sheets. The` rolls 12, 15, 16, 17, 18, 19 and 2O are positively driven by any suitable means. In the present instance I have illustrated a pulley 2.5 driven by a belt 26 from an electric or other motor, not shown. The pulley 25 is mounted upon shaft 27 which carries a gear 28, the latter-meshing with idlers 29v and 30. Idler 29 meshes with a gear fast upon roll 12, and idler 30 meshes with a gearv fast upon roll 16, and all of the rolls 15,16, 17, 18, 19 and 20 are intergeared to travel at uniform speed.

The fold plates 21, 23and 24 are each provided with a deilector bar 31 that is secured at its ends to arms 32, the latter being pivotally mountedupon aligned studs 33 which are threaded into bosses 34 protruding from the upper surfaces of the respective fold plates. In the drawings these deiectors are shown vthrown back into their inoperative positions upon the upper surfaces of the plates, the plates being in their forward or folding position. Y

In the case of the fold plate 22,l the feed .table 1,1 is located so lclosely above it that there would` be insuilicient space for the use of a deflector bar 31 having pivoted arms 32.

i tive positions.

In this location therefore I employ my present invention, wherein the deflector slides over the top surface of the fold plate. Near the sides of the fold plate a short distance beyond the nose thereof, I form two bosses into which are threaded aligned studs or pivot pins 36, similar to the studs 33 previously mentioned. Slidably and pivotally mounted upon these pins 3G are slotted arms 37 which are secured at their forward ends to the eX- tremities of a deflector bar 38.

In its inoperative position the bar 38 engages behind two small pins 39 protruding upwardly from the fold plate 22, the forward end of the slot in each of the arms 37 at this time engaging the pins 3G, so that movement in either direction is prevented. When the deflector bar 38 is in its operative position, illustrated in Fig. 4, a shoulder at the bottom of each arm 37 engages the front edge of a laterally projecting block 4l on the fold plate.

Each of the fold plates 2l, 22, 23 and 24 has parallel runners 42 at its side edges which ride upon rails 43 of angle bar form, the vertical fianges of these rails being bolted or otherwise secured to the frame l() of the machine. The fold plates are thus slidable toward and from the fold rolls. Their movement inward is limited by the engagement of the forward ends of the runners 42 with stops 44 on the frame, as illustrated in Fig. 2. These stops come into use only when the deflectors are in their retracted or inoperalVhen the defiectors are in their forward or operative positions the movement of the fold plates forward upon their rails 43 is limited by the engagement of the arms 32 or the arms 37, as the case may be, with stop pins also mounted upon the machine frame.

Assuming that the parts are in the position illustrated in Figs. l, 2 and 3 of the drawings, the fold plate 22 being in the position for imparting a fold, and assuming that the operator desires to disable this fold plate, he first grasps the fold plate and slides it backward upon the supporting and guiding rails 43 until the fold rolls 16 and i8 have been cleared. He then pushes downwardly upon the arms 37 or upwardly upon the dellector bar 38 in order to tilt the deflector upon the pins 36 sufficiently to lift its forward end over the tops of the stop pins 39. The deiiector is then slid forward until the shoulders 40 on the arms 37 drop down in front of the forward edge of the blocks At this time the deflector bar 38 has travelled forwardly far enough to clear the nose of the fold plate, so that it is free to descend in front of the latter and cover the intake slot of the plate. In this position of the defieetor it is held from movement in either direction, tiiat is to say the engagement of the pins 3G with the rear ends of the arm slots prevents forward motion, and the engagement of the shoulders 40 with the forward edges of the blocks 4l prevents rearward movement. T he fold plate is now slid forward until the for ward ends of the slotted arms 37 engage the stop pins 45, when the del'lectors are in proper position with respect to the rails 16, 17 and "i8 to direct sheets of paper passing between rolls 16 and 17 through a curved path into rolls 17 and 18. This position of the parts is illustrated in Fig. 4.

Now when it becomes necessary to again put the fold plate 22 into commission, it is slid back out of the way of the fold rolls, the deflector bar 38 is lifted suiciently to clear the nose of the plate, causing the shoulders 40 on the arms to clear the blocks 4l, after which the deflector may be slid rearwardly. In case the bar strikes upon the forward side of the stop pins 39, a slight tilting of the deflector upon its pins 36 serves to clear this obstacle, and the rearward movement can then be continued. When it has proceeded as far as the pin and slot connection will permit, the operator releases his hold and the deflector bar moves downwardly into position behind the stop pins 39, when it is again held against movement either forwardly or backwardly by the stop pins and the pin and slot connection. The deflector being thus set in inoperative position, the operator slides the fold plate forwardly until the runners 42 strike against the stops 44, as shown in Fig. 2, when the plate is in proper position for the folding operation.

While in the foregoing description and in the accompanying drawings I have disclosed more or less in detail one particular form of the invention, I desire it to be understood that such detail disclosure has been resorted to primarily for the purpose of fully illustrating the invention and is not to be construed as amounting to a limitation upon the scope thereof.

Having thus described my claim:
